On Wednesday, not only was Thor hunk Chris Hemsworth caught shirtless in St. Barths, but Justin Bieber posted a photo of himself (sans shirt!) on his Instagram account. Now we know it might not seem fair considering Chris has the bod of a superhero (literally) but we have to admit, the Biebs has definitely bulked up recently.
So, who do YOU think looks better shirtless? Cast your vote in the poll to let your voice be heard!
While we love JB, our money is on Hemsworth! Just look at those abs! Check out some more shirtless photos of him below!
